Is Increased Capillary Permeability?

If capillary permeability is increased, as in inflammation, proteins and large molecules are lost into the interstitial fluid. This decreases the oncotic

oncotic
Oncotic pressure, or colloid osmotic-pressure, is a form of osmotic pressure induced by the proteins, notably albumin, in a blood vessel's plasma (blood/liquid) that displaces water molecules, thus creating a relative water molecule deficit with water molecules moving back into the circulatory system within the lower ...

pressure gradient and so the hydrostatic pressure in the capillaries forces out more water, increasing the production of the tissue fluid.

What does increased vascular permeability cause?

The resulting increased vascular permeability allows increased transport of proteins through the capillary vessel wall and results in increased COP in the tissue.

Does inflammation increased capillary permeability?

The acute inflammatory response consists of three main vascular effects: vasodilatation and increased blood flow, increased vascular permeability, and leucocytosis into the injured tissues.
